T, all who e 'i3 'may concern.' A Be ii known that l, Geenen Mooier, e citizen of tlie United Stiles, residing et Joplin, in the county of Jesper und Stute of Missouri, here invented certain new audhuseful Improvements in Filters; and l do hereby decla-re the 'ollowing to lie e. full, clear, and

exact description of rice invent-ion, such as Willeneble others skilled in the artic which it appertains to ineke and use the sinne.

4My lriveniion relaies J(o.iniprm'ements in filtering apparatus, and particularly to the' vided .at its upperend with supply'pipe.

'the operation, and oy irancli pipe 5b with pump 6" for passing u reverse current through seid 'filter during the .discharge of llie"solids collected thereon, es'will hereineier fully appear. Valve 5a is` disposed in clic lengtliof pipe 5 for controlling oomumnirution with pump 6, end pipe h connects with pipe ilietiyeen the valve 5 and the il'ter'pu'bes. .ai- Valve 5 is disposed in the brunch 5* to control Acommunieation .v thereof with pump 6. Tlieoliamber l is I mouniedupon any suitable, fixed brackets 7, '7 andrelained-by-tlie vseine in e given position.l A preferably iunnel-slioped heed -ordischargedoor 8,' having an annular, outwardly exending Hange- 25, normally closes the lower end of the chamber 1,:said chamloer l being formed at Lits lower`iend with a similar flange 26, and seid head rests upon any suituble carrie e 9 positioned to travel upon tracks'll, seiA head being arranged to slide beneath the lower end 'of said chamber l and being free to move from beneath the saine Whenever desired. A suitable, annular packing or geskeil 27 is' preferably can Yried by the iange 26, and seid flanges 25 and 26 are adapted, when the parts are in ille position imlioeted in Fig. l, 13o-oe locked to- .get-lier by means of the clamps' 28. The lower end of the tapered or funnel-shaped' heed 8 is'provided with any suitable controlling valve ll .for preventing the dise charge ci the'ineterials within the chamber when desired. 'As -will be observed by refer*- ence to Fig. the pluies l may be substituted by tubular filters 4 in any suitable number and arranged ori'acilitating Alie drawing of materiel through the liltering medium carried by said tubes.

in operfiiion, the. metal bearing pulp is introduced under pressure through the pipe from pressure bunk 2 into the chamberl, such pressure being sufficient for forcing the liquids from seidpulp throuigh lter pletes al -or 'tubes el', until the said plates or tubes, as 'the case may be, become 'coated with solids, as indicated iii dotted lines in the drawing, said coating never beingpermitted to become thick enough to entirely close the spaces between elle several plates or between Vt ie plates or tubes and the contiguous Walls' of chamber l. At liis point, the surplus pulp is allowed to How out through Valve 11,

the Vacuum pump being vbrought'into operation for holdin the slime cakes in position on thel filter sui-ieee, and a dissolving Huid is introduced through lie pipe 2, followed by u cleansing lluid, as' Water,and the sired degree, the valye il rising opened for ico bottom of the cham permitting the excess liuids within the chamber l to escape at libe close of each operation, and said valve being closed i"or the next operation. The drawingaction through pipe 5 is continued during,r the escape of tie liquid through the valve ll and also While head 8 is being moved along the track l0. As soon as head 8 has been removed from beneath chamber l, the pumping action is stopped, and air is permitted to enter the filter plates d through the pipe 5 either under pressur or not7 as may be desired. It desired, air is introduced under pressure from pump 6', and the solids Will fall from the ltering; medium into any suit able receptacle below. However, it isl not absolutely necessary that the air introduced should be under pressure, for the reason thatA the weight of the solids clinging to the iltering medium is usually sufiicient to cause such solids to drop from 'the filters when released by the admission of atmosphere, and consequent relief ofvacuum Within the filters. After the solids have been discharged, the head is returned'to its former position, and the operation may be repeated. -By this structure l am enabled to remove all, or substantially all of, the precious metals from slimes in the most expeditious manner While facilitating the disposition of the solids after their cleansing.

During the operation, as above set forth, it is found that, unless some means are provided, 'to prevent clogging of the heavier substances Within the bottom head 8, the settling of sands, during one operation Will he sulicient for lilling such bottom and closing up the spaces between the plates 4: at their lower ends, and, in order to prevent such clogging, .l contemplate leaving the valve ll slightly open during the building upv of the cakes or coatings of solids on the filter flutes, not, however, to a sulicient extent 'or relieving the pressure Within the chamber l, whereby the settled portions of solids -vvill be removed as the same descend into the bottom 8. Gf course, the portions that are discharged in this manner through valve 11 may,be returned to the original source of supply for further treatment. That is to say, the discharged slimes may be directed bach to the chamber 1 by any suitable conveyer, as by a return pipe 30 extend ing from below the valve 11 to a force pump 3l Which 'communicates by a pipe 32 Wit the tank'2. ,A funnel 33 may receive the discharge and deliver the same to the pipe 30. The pipe 32 is referabl branched as at Bil and 35 tor facilitating suitable disposal of the discharged dissolving fluid and cleansing liuid respectively. n It is to be observed that the outflow through pipe 5 andLthe discharge from the er Il combined With the introduction of pulp into the chamber under Leonesa pressure will keep the pulp in the chamber in movement, such movement being suliicient te maintain the iuid portion of the pulp in a condition adapting it for mlvantageous filtration. Obviously, though some of the heavier sands may drop to the bottom of the chamber, no pronounced line of strrditiccn tion Will a pear owing to the movement of the free' pu p, and cultes will be built up on the filtering material possessing substantially uniform resistance to the passage therethrough of fluid. It is also th be noted that the filtering tubes or plates are so arranged that the cakes of solids built up thereon will not adhere to the Walls of the chamber, but will readily fall from the chamber when freed from the filtering medium. The clamps 28 serve as jacks for drawing; the

bottom head 8 up into close contact with the )aching or gasket 27, Obviously when the bolts or clamps 28 are threaded torpressin(r against flange 2G, the bent members oi saiil clamps ii/ill act as follower means which Will exert pressure on bottom 8 and on the bolts of the clamps simultaneously in opposite directions.
